1. Functions of add-on items

  • Creating a discount combo of product and add-on item

Add-on Items is one of the effective ways to boost up your sales. You can assign at most 5 add-on items to one main product. 

  • Set customer purchase restrictions

You can decide to set up limitations for add-on items. Unlimited add-on items setting is suitable for items with a low price and a larger inventory.

    • Limitation ON: Customers can buy add-on items together with the main product but the number of add-on items cannot be more than the quantity of the main product.
      (Note: only applicable on product-level add-on items. Add-on items to the shopping cart are not restricted)
    • Limitation OFF: Customer needs to purchase a least one main product for purchasing an unlimited amount of add-on items (with the upper limit from the inventory)
  • Excluded from any store discount

As an add-on item is already a discounted item, it cannot be further discounted.

*Please note:
One main product can be paired with 5 add-on items at most. It means when you visit the product page, it shows up with 5 add-on items. The priority sorting does not follow the sequence of add-on product's uploaded/created time and date, it currently depends on time of pairing with a main product. But you can manually modify the priority order of the add-on products if you wish.

For example: 

  1. Created the add-on items A > B > C.
  2. Main product 1 paired with C first, then paired with A, then B.
  3. On the storefront page of product 1, it displays the ordering C > A > B from above to below.
